An improved folding marker for an agricultural implement that is partially self-supporting in the use position and during a portion of the folding operation. An inner arm is pivotally attached to the agricultural implement for simultaneous movement in both the horizonal and vertical directions. A caster wheel is attached to the inner arm to support the inner arm above the ground. An outer arm is pivotally attached to the inner arm for movement in a generally vertical direction. A marker device is attached to the outer arm for scoring the ground. An actuator is attached to the implement and the back portion of the inner arm for moving the inner arm between the use position and backwards toward the rear of the implement to a transport position. A series of pulley systems are attached to the marker so that the inner and outer arms raise vertically upward when the inner arm is moved from the use position to the transport position, and vice versa.
